Definitions

  • the present invention relates in the first place to a proceeding, for a hoistable deck for cargo in ships which is lifted by means of a scissor lift or any other lifting device, to achieve the lifting up of hanging down portions of said deck for cargo to a height, which is sufficient to fold out/retract the supports of the ship to support said deck for cargo.
  • Hoistable decks for cargo on board ships which above all are used to support vehicles on desired levels in cargo spaces on board the ships in guestion, and which are formed by a number of vertically movable decks for cargos, are in the simplest possible way lifted by means of devices for lifting decks in the form of scissor lifts, which are driven on the deck located below the deck in question to be lifted.
  • said devices for lifting decks lift the decks in question to the correct desired level, where they are supported by means of controllable supports acting between the cargo space of the ship and said deck for loading vehicles.
  • Another way of lifting decks for cargo is to use a hoist device, whereby hoist ropes located along the cargo spaces in question, where the decks for cargo are accommodated, are hoisted to the desired levels and locked to support cargo and to stow, respectively.
  • the mechanism in question could effectively lift any other part of decks for vehicle cargo, which is hanging down, as long as the mechanism is placed exactly in the area, in which the part is hanging down .
  • the main object of the present invention is, therefore, in the first place to reduce the air slot/ margin of "over-lift" as much as possible, but is shall still be possible to use the conventional decks for vehicle cargo and scissor lifts which are now available on the market.
  • a proceeding according to the present invention which is mainly characterized in that by the lifting movement of the deck for cargo a mechanically acting loadable mechanism is released, which is loaded by the downward or upward movement of the deck for vehicle cargo, whereby the hanging down parts of the deck for cargo are forcibly lifted up by the actuation of an actuation part and a lifting part, respectively, which are co-operating between said deck for cargo and the ship, whereby a lever with multiple arms is pivoted by co-operation with actuation stop and dolly stop, respectively, in order to induce the mechanism to release by setting said deck for cargo in motion and bring about lifting up of hanging down part of the deck for vehicle cargo.
  • the invention also relates to an arrangement, which is suitable to be used for carrying out a proceeding according to the invention, and according to the kind indicated above.
  • the invention relates to a fully automatic "pressing-up-mechanism" which, for example, is placed in the hanging down corners or in another place, and when it passes stationary
  • Fig. 1 shows a hoistable deck for cargo in lifted up position and locked on correct level
  • Figs. 2-7 illustrate different sequences of a hoistable deck for cargo during its lifting position, lifting up of the corners and supporting position,
  • Fig. 8 illustrates schematically a scissor lift under a hoistable deck for vehicle cargo
  • Figs. 9-11 show a variant of lifting device in various positions.
  • the idea of the invention is that a spring etc. is loaded when the arrangement passes a shoulder in the ship when the deck is on its way downwards, and then, on the way upwards, changes and catches the upper side of the shoulder, so that the loaded spring is released and thereby generates a force that is strong enough to rotate and lift the corner of the deck.
  • the deck for cargo is lifted up by means of a scissor lift.
  • the supports are retracted and the deck can now be lowered by means of the scissor lift.
  • a proceeding according to the present invention comprises to, at hoistable and on desired level 8 on support 9 supportable deck for cargo 1 on board ship 2, achieve lifting up 3 of corners and other hanging down portions 4 of the hoistable deck for cargo 1 in question, which is lifted up 5 and lowered 6, respectively, by means of a scissor lift 7 or any other lifting device.
  • a mechanically acting loadable mechanism 11 is released, which in the illustrated embodiment consists of a helical spring with pressure function and which is loaded by the downward or upward movement 6, 5 of the deck for vehicle cargo 1.
  • the lever 17 is pivoted through co-operation with actuation stop 22 and dolly stop 23, respectively, in order to load I and release II, respectively, the mechanism 11 by moving said deck for cargo 1 and thereby cause lifting 3 of hanging down 4 portion of the deck for cargo 1 which co-operates with the arrangement 21, preferably the corners 4 of the deck for vehicle cargo, but also for example intermediate or other hanging down portions of said deck for vehicle cargo can be lifted up when
  • An arrangement 21 according to the present invention adapted to, at deck for cargo 1 in ship 2, lift up 3 hanging down parts 4 of said deck for cargo, which is lifted up 5 and lowered 6, respectively, by means of a scissor lift 7 or another lifting device acting on the underside 10 of and/or along the peripheral edge of said deck for cargo 1, such as for example ropes, comprises a mechanically acting loadable mechanism 11 for accumulating energy.
  • This mechanism 11 is arranged to, by means of automatic actuation from between the cargo space 24 of the ship and the deck for cargo 1 in question located actua- tion part 12 and lifting part 13, respectively, actuate the mechanism 11 to be released for subsequent forcible lifting up 3 of the hanging down part 4 of the deck for cargo to a level, which makes it possible to fold out/ retract the ordinary supports 9 of the ship to support said deck for cargo 1.
  • Said loadable mechanical mechanism 11 is arranged to be loaded by the downward or upward movement 6, 5 of the deck for cargo 1.
  • Such a mechanism 11 consists preferably of a spring, a helical spring of the compression spring type, but it is also possible to use a tension spring if the direction of the spring force is correct, or of other mechanical loadable known types of mechanisms.
  • the mecha- nism 11 illustrated consists of a compression spring, which can be stretched S and released U, respectively, by actuation.
  • Mounting articulations 15, 16 for said loadable mechanism 11 and mounting articulations 14, 15 for said lever 17 are arranged to have overcenter locking function L, see Figs. 2 and 3, in a certain pivoting position for the lever 17 and the loadable mechanism 11, and thereby automatically hold the mechanism in locked loaded position, but still be in a position ready to be released and without it being necessary to arrange any additional locking means.
  • such a lever 17 consists of a lever with multiple arms, which is pivotably mounted around a shaft 14 and comprises an attachment 15 for the loadable mechanism 11, and an actuation part 12 for co- operation with an actuation stop 22 and a lifting part 13 for co-operation with a dolly stop 23.
  • Said lever 17 is arranged to be forcibly pivoted around its mounting shaft 14 through co-operation between the actuation part 12 and an actuation stop 22, after actuation by the loadable mechanism 11 and through co-operation between the lifting part 13 and the dolly stop 23.
  • the actuation part 12 consists of a rotatable wheel or a rotatable roll, and the actuation part 12 and the lifting part 13, respectively, are arranged to bear on a wedge-shaped portion along its oblique lower surface 22 and on its straight upper surface 23, respectively.
